## Signal Details

### The `"trigger"` signal

    void                user_function                      (IBusHotkeyProfile *profile,
                                                            guint              event,

                                                            gpointer           user_data)      : Has Details

Emitted when a hotkey is pressed and the hotkey is in profile. Implement the member function `trigger()` in extended class to receive this signal.

### Note

The last parameter, user_data is not actually a valid parameter. It is displayed because of GtkDoc bug.

`profile` : | An IBusHotkeyProfile.
`event` : | An event in GQuark.
`user_data` : | User data for callback.
`user_data` : | user data set when the signal handler was connected.
